The 'Avatar' star was arrested on Saturday (03.11.12) for allegedly fighting and had to be subdued with pepper spray.

A police source told gossip website TMZ.com that the actor got into a violent argument outside The Vortex bar in Atlanta, Georgia, over the weekend after he was refused entry for being intoxicated and failing to produce any ID.

According to the official report, an eyewitness told police officers that the 36-year-old actor, who is currently in Atlanta filming his new movie 'Ten' alongside Arnold Schwarzenegger, became disorderly and allegedly pushed the club's doorman twice before he was pepper sprayed and restrained by security staff at the bar.

The incident is said to have been captured in full by the bar's security cameras and Sam was put in handcuffs until police arrived at the scene and arrested him.

Earlier this year, Sam said he was trying to live a calmer life and admitted he can be a very difficult person to live with.

He said: "I think I'm still a very difficult person to live with, because my motor's always running but as you get older you try to slow down and live life at a calmer pace."

Although Sam is from Perth, Australia, he has recently put down roots in Hawaii by buying a home because his dog needed somewhere to live.
